Hereinafter, by “leaving group”, we mean a group that can easily becleaved from a molecule by rupture of a heterolytic bond, with departureof an electron pair. This group can thus be replaced easily by anothergroup during a substitution reaction, for example. Said leaving groupsare, for example, the halogens or an activated hydroxyl group such as amethanesulfonate, benzenesulfonate, p-toluenesulfonate, triflate,acetate, etc. Examples of leaving groups as well as references for theirpreparation are given in “Advances in Organic Chemistry”, J. March,5^(th) Edition, Wiley Interscience, 2001.

In accordance with the invention, the compounds of general formula (I)can be prepared according to the method shown below in Scheme 1.

According to Scheme 1, the compounds of general formula (IV) can beobtained by reaction of a compound of general formula (II) in which X isas defined in general formula (I) and B represents a C₁-C₆-alkoxylgroup, with a compound of general formula (III), in which Y and n are asdefined in general formula (I) and GP represents a leaving group or GPrepresents a hydroxyl group.

Test of Inhibition of the Current Induced by Capsaicin on the Rat DRG

Primary Culture of Rat Dorsal Root Ganglion (DRG) Cells:

The neurons of the DRG express the TRPV1 receptor naturally.

Primary cultures of DRG of neonate rats are prepared from 1-day-oldrats. Briefly, after dissection, the ganglia are trypsinized and thecells are dissociated mechanically by careful trituration. The cells areresuspended in Eagle's basic culture medium containing 10% of fetal calfserum, 25 mM KCl, 2 mM glutamine, 100 μg/ml gentamicin and 50 ng/ml ofNGF, then deposited on glass slides covered with laminin (0.25×10⁶ cellsper slide), which are then placed in Corning 12-well plates. The cellsare incubated at 37° C. in a humidified atmosphere containing 5% CO₂ and95% air. Cytosine β-D-arabinoside (1 μM) is added 48 h after cultureset-up, to prevent the development of non-neuronal cells. The slides aretransferred to the test chambers for patch-clamp investigations after7-10 days in culture.

Electrophysiology:

The measuring chambers (volume 800 μl) containing the cellularpreparation are placed on the stage of an inverted microscope (OlympusIMT2) fitted with Hoffman optics (Modulation Contrast, New York) and areobserved at magnification of 400×. The chambers are continually perfusedby gravity (2.5 ml/min) by means of a solution distributor accepting 8inlets and whose single outlet, comprising a polyethylene tube (insidediameter 500 μm) is positioned at less than 3 mm from the cell underinvestigation. The “whole-cell” configuration of the patch-clamptechnique was used. Pipettes of borosilicate glass (resistance 5-10MOhms) are brought up to the cell by means of a piezoelectric 3Dmicromanipulator (Burleigh, PC1000). The total currents (membranepotential fixed at −60 mV) were recorded with an Axopatch 1D amplifier(Axon Instruments, Foster City, Calif.), connected to a PC controlled byPclamp8 software (Axon Instrument). The current traces are recorded onpaper and simultaneously digitized (sampling frequency 15 to 25 Hz) andsaved to the hard disk of the PC.

The application of a micromolar solution of capsaicin induces a cationicinput current on the DRG cells (voltage fixed at −70 mV). In order tominimize the desensitization of the receptors, a minimum interval of oneminute is observed between two applications of capsaicin. After acontrol period (stabilization of the capsaicin response alone), the testcompounds are applied alone at a specified concentration (concentrationof 10 nM or of 0.1 nM) for a duration of 4 to 5 minutes, during whichseveral capsaicin+compound tests are performed (for obtaining maximuminhibition). The results are expressed as percentage inhibition of thecapsaicin control response.

The percentage inhibition of the capsaicin response (1 microM) isbetween 20% and 100% for the most active compounds of the inventiontested at a concentration from 10 nM to 0.1 nM (see example in Table 5).

The compounds of the invention are therefore effective antagonists invitro of the type TRPV1 receptors.

Mouse Cornea Irritation Test

The irritant nature of capsaicin is easily appreciated at the level ofthe cornea since this organ is one of the most innervated with theC-fibres. In this context, according to preliminary experiments, theapplication of a very small amount of capsaicin (2 μl at a concentrationof 160 μM) to the surface of the cornea of an animal leads to a certainnumber of stereotypical behaviors associated with irritation, which areeasily listed. These include: blinking, rubbing of the instilled eye bythe ipsilateral forepaw, rubbing of the face with both forepaws,scratching of the ipsilateral face by the hindpaw. The duration of thesebehaviors does not exceed 2 minutes of observation, and the animal thenresumes its normal activity. Moreover, its appearance is also normal.The mouse does not retreat to a corner with its hair standing on end,and does not develop any observable sign of suffering. It can beconcluded that the duration of action of capsaicin at these doses isless than 2 minutes.

Summary of the Methodology:

The principle of the series of tests is to determine whether thecompounds of the invention can influence the behavioral response inducedby a specified amount of capsaicin. The capsaicin is initially dilutedto 25 mM in DMSO and diluted, for final use, in physiological serum withTween 80 at 10%. It appears, from control studies, that in theseconditions the solvent has no effect.

In practice, the test product, prepared at 25 mM in DMSO and diluted forfinal use in physiological serum with 10% of Tween 80 at the strongestconcentration of 500 μM, is administered by local application to thesurface of the cornea at a volume of 2 μl, 10 minutes before applicationof the capsaicin. The animal receives an ocular instillation of 2 μl ofa 160 μM capsaicin solution prepared as stated above. For an observationperiod of 2 minutes following instillation, the number of times theinstilled eye is rubbed by the ipsilateral forepaw is counted for eachanimal.

For a given group, the percentage protection is calculated as follows:

P=100−((average number of scratchings of the group treated with thecompound/average number of scratchings of the group treated with thesolvent)×100)

This percentage protection is averaged for each group of animals(n=number of animals tested with the compound of the invention).

The percentage protection evaluated, in this model, for the most activecompounds of the invention, used at a concentration of 500 μM, isbetween 20% and 100% (see example in Table 6):

TABLE 6 Compound No. % P 500 μM 1 51% 3 34% 6 30% 9 43% 12 83%

The results of these tests show that the most active compounds of theinvention block the effects induced by stimulation of the TRPV1receptors.
